This has been something that's been on my mind recently due to the number of shows, books and other mediums I've been consuming.
I'll preface this by saying that this isn't me saying that "these characters are secretly ABs/Littles in the canon of their series" Rather, it's the traits that they exhibit in numerous instances that seem like they could seemingly be fit into an AB/Little lifestyle.
For me, one that comes to mind is the character Peridot from Steven Universe. Mind you, a lot of my thoughts on her seeming like an AB/Little is derived from how she's presented in the show itself, ranging from her attire, her mannerisms and the circumstances she finds herself in. Most notable instances of this include her being strapped into a child's leash, a comment made by her to which she referred to herself as a "certified kindergartner" and an unused series of storyboards for the show where she was shown to be eating out of a highchair.
But my thoughts on her fitting into an AB/Little role is also based on her personality, where she can be bratty and arrogant, but also has levels of child-like curiosity and some choice moments of wanting to seek approval from those around her.
What do you guys think? Are there any characters from series you regularly partake in that may seem like they could easily be an AB/Little?
